US Energy Secretary Clarifies Nuclear Weapon Testing

Imagine that to make sure a toy is working perfectly, you might shake it or press its buttons, but you don't break it.

The United States has big, powerful toys called nuclear weapons.

For a long time, the U.S. didn't test these powerful toys by setting them off.

Recently, President Trump said he wanted to start testing them again, which made other countries like China and Russia pay attention.

However, the Energy Secretary explained that these tests won't be actual big explosions of the nuclear bombs themselves.

Instead, they will be like checking the parts of the toy to make sure they work right, to build even better ones for the future.

The U.S. can also use computers to pretend to have the big explosions to understand them.
